COMBINED TRUCK-FRAME AND JOURNAL-BOX.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed. December 20, 1913. Serial No. 808,037.

To all whom it may concern Be it known that 1, Ivan A. R-ANDEL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Combined Trucklirames and Journal-Boxes; and I. do hereby declare the following to be a full, clear, and exact description of the inventiton, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to car trucks and has for its particular object to provide an improved casttruck side frame having perma nently secured journal boxes, and to such ends, generally stated, the invention consists of the novel construction and arrangement of parts hereinafter described and defined in the claims.

In my prior Patent No. 1,077,159, of date, October "28th, 1913, entitled Journal box, l broadly claim a journal box comprising an independently formed metallic cellar and a top made fast to the cellar by the metal of the top in the forming thereof. The present invention involves this feature of construction, but goes further, in that it makes the journal box tops integral parts of the truck side frames. Stated more specifically. the independently formed metallic journal box cellars are first formed and then the side frames are cast with integral top forming end portions that are cast fast to the said independently formed cellar. The side frames are preferably steel castings and the independently formed metallic journal box cellars are preferably pressed into form, out of commercial sheets of steel.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure l is a view chiefly in side elevation with some parts sectioned, showing one of the truck side frames with permanently secured journal boxes, the truck wheel being shown in diagram; Fig. 2 is a section taken on the irregular line m m on Fig. 1; Fig. 3 is an enlarged fragmentary section taken on the same line as Fig. 2; and Fig. #1 is a fragmentary View partly in plan and partly in horizontal section on the line m" (0* on Fig. 1.

In the construction illustrated, the pressed steel cellar of the journal box is formed with an integral inner-end outside dust guard wall 2 having the usual large 'axle passage A separately formed inside dust guard wall 4 is also advisably constructed from sheet steel and is preferably provided with a flange 5 on its lower edge. To adapt the cellar to receive the dust guard, not shown, between its inside and. outside dust guard walls, its inner end portion is slightly expanded, thereby forming a vertical shoulder against which the inside dust guard wall 4: is arranged to be seated. When the inside dust guard wall 4 is inserted into the cellar, its flange 5 will hold it properly spaced from the outside dust guard wall 3. The upper edge of the cellar and of the inner dust guard wall a are preferably made means of slits 6 indicated by dotted lines in Fig. 2; and to provide for an interlocking connection between the said cellar and wall 4t and the top forming end portions of the cast side frame, said cellar and wall, near their upper edges, are provided with perforations 7, into which the cast metal will run, all as more fully disclosed in my copending application, Serial Number 795,513, filed of date, October tled Journal box.

hen the cellar and its inner dust guard wall have been properly assembled and properly presented to a mold or flask, provided for the casting of the side frame, the

molten metal for forming the side frame 15 poured into the mold cavity and the side frame 8, with its top forming ends 9, is cast. Between the upper edges of the dust guard walls 3 and 1, the top forming ends 9 of the east side frames are formed with a vertical passage 10 which permits the dust guards, not shown, to be inserted into the journal box between the said Walls. At the outer ends of the cellars, the end forming portions 9 of the side frames are providedwith integral hinge lugs 11, to which journal box lids 19 of suitable construction are pivoted.

The pressed steel cellars 1 are advisably formed with outwardly pressed corrugations 13 that stiifen the collars, and at their lower portions, join with depressed bosses 1-1. which latter afford bearings for the application of lifting jacks. The upper portions of the stiffening corrugations 13 are preferably embedded in depending portions 15 formed integral with or as part of 16th, 1913, and entiabnormally contractible by og 7i ,1523

the top forming ends 9 of the side frames. These depending portions 15 give great rigidity to the central portion of the cellar and the inside members of the said portions 15 join integrally with the end portions of the trussed side frame proper and give greater strength at the point of union between the said thrust side frames proper and the journal hex forming elements.

In punching holes in sheet steel, they are naturally made with a taper. This taper, which is slightly exaggerated in F 3, is taken advantage oi to form dove-tailed or rivet-like interlocking connections between the sheet metal ,cellar and its inner dust guard Wall and the cast metal of the side frame.

Combined side frame and journal boxes constructed as above described, may he made at comparatively small cost and are very strong and durable. The cellars, While not in their full sense, integral parts of the side frames, are nevertheless, permanently united therewith by substantially integral joints which do not permit of any initial relative nio entient oi the elements of the side frame and journal boxes From such constrn tion, it that the constant and severe jars and gounfling action to which the side and journal boxes are subjected in 2 frames service, can not loosen up any of the said connected parts in respect to the other. T his .iportant because the jars in acce will loosen up and produce Play between that are not in eject,

' .tegrally united.

4'- t claim is:

l. A c st truck side frame provided with independently formed metallic journal box cellars that are primarily Without tops, the said frame having integral portions fast to the upper edge portions of said cellars and constituting the tops of the journal boxes a 2. A cast truck side frame provided wit 'pressed metal journal box cellars and lltV- upper edges of ing integral one portions cast fast to the i said collars and constituting the tops of journal boxes.

3. 12. cast truck side iramc provided with independently formed pressed sheet metal journal box cellars having their upper edges slit, the said side frame having integral end portions cast fast on the slit upper edge portions of said collars and constituting the tops of the jl'llllllll boxes, the said slit edges of said cellars being almormally contracted.

i. A cast truck side lrzuno provided with indepelulently formed metallic journal box cellars and having integral end portions cast fast to said. collars and constituting the tops of the journal boxes, the said integral end portions having: openings for the in sertion oi dust gum-(ls.
